Letter from Dr. Milton Lewis, Richland Section, American Chemical Society, to LP RE: Pleased to hear that LP will address the Richland Section on November 5. Will make hotel reservations for LP for November 4 and 5. Offers to arrange a meeting with officials or technical personnel of the General Electric Company or the Atomic Energy Commission. If LP has the necessary clearances, he can take a guided tour of the plant. Requests the subject of LP's talk. Wonder if LP would also present a brief after-dinner talk on a non-technical subject close to his heart. [Letter from LP to Lewis September 28, 1956] [Filed under LP Speeches: 1956s.34]

Letter from LP to A. I. Oparin, Institute of Biochemistry, RE: Writes that he will be coming to the symposium on the Origin of Life and suggests that one of his colleagues, Norman Horowitz, be invited as well, for the important contributions to the subject he has made. Also mentions several other possible people to invite. [Letters from Oparin to LP August 24, 1956, October 12, 1956] [Filed under LP Speeches: 1957s2.1]

Let me answer the question in the last paragraph of your letter of 10 September first. When I heard your talk about Humanism in Los Angeles a few months ago, I decided that I am a Humanist. I think that I told you at the time that your talk was a wonderfully precise and illuminating discussion of the subject. I am glad to repeat this statement now.

I am pleased that you have got a copy of my book GENERAL CHEMISTRY - I wish that I had sent it to you. I hope that you find severa [sic] sections worth reading. Have you read the chapter on biochemistry? I think that it is pretty good.

I have some trouble in answering your questions about energy and matter. I have several times tried to understand philosophy. I have never had much success. As to the statement that I made that the universe is composed of substances (forms of matter) and radiant energy, I would say that the aspects of energy that you are thinking of - latent heat of fusion, chemical energy, and so on - are included in ay category of substance. I do not think that it is sensible to say that a piece of sugar is something more than the substance sugar. It is true that the substance sugar at 25° C is different in its properties than the substance sugar at 0° C; but the differences between the two samples of matter cannot be simply attributed to something else, energy, in the sugar. Radiant energy, on the other hand, is not associated with substance, although, of course, it has mass. I have thought it worth while to restrict the word substance to those aspects of nature that have finite rest mass.

One complication that you have to worry about is that the kinetic energy of a moving body depends upon the frame of reference.

I do not feel very happy about the expression matter-energy.

Sincerely yours,

Linus Pauling:W
